Filed: 1928-03-16
Abstract: 315,895. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). March 16, 1928. Grant of Patent revoked. Hydrocarbons.-Gaseous unsaturated hydrocarbons are obtained from oils, tars &c. by heating the initial materials up to 600-800‹ C. in the presence or not of cracking catalysts and gases such as water vapour, separating condensates from the resulting gases by fractional liquefaction, or by the application cf pressure and by cooling in stages and rectifying the said condensates by fractional distillation. Equal parts by weight of gas-oil and water vapour are passed over an alloy of iron, chromium and nickel. From 1 metric ton of oil a gas mixture is obtained comprising 200 kgs. ethylene, 150 kgs. propylene, 50 kgs. amylene and butylene and 200 kgs. of a mixture of methane, carbon monoxide and nitrogen, besides about 360 kgs. of liquid products consisting mainly of benzines and tar. The gaseous products are separated by compression to 200 atmospheres and cooling to - 10‹ C., further cooling to -90‹ C. and finally to -120‹ C., whereupon the pressure is released and the remaining gases cool down to a very low temperature and are utilized for cocling in the earlier stages. The condensates thus obtained are rectified in columns and ethylene and propylene of 90 per cent purity are obtained. Specifications 248,375 and 251,652 are referred to.

Title: Method for the treatment of workpiece surfaces and apparatus for the perfomance of the aforesaid method
IPC: B24B31/00
Filed: 1972-02-22
Abstract: 1379621 Tumbling O PLETSCHER and T PLETSCHER [trading as PLETSCHER GEBR] 22 Feb 1972 [22 Feb 1971] 8180/72 Heading B3D A method of treating the surfaces of workpieces 19 by means of a mass of smooth-surface or abrasive particles 18 comprises placing the particles into a state of free fall, and in the presence of a friction-reducing medium causing the particles to impact upon and then slide along the surface of the workpiece. In apparatus for carrying out the method, the particles and workpieces are fed into one end of a drum 1 which is rotatable about an axis slightly inclined to the horizontal in support rollers, the inclination causing the workpieces to move along the drum and out the other end. The ends of the drum are connected by sliding face seals 11, Fig. 4, to angled or flexed inlet and outlet conduits, respectively. The inner surface of the drum is lined with rubber, plastic, wood or like material 3 formed with ribs 5 and grooves 4. Ribs 15 at the end of the drum form a trough 16 in the drum for retaining the friction-reducing medium, such as a liquid lubricant. When the drum is rotated, the particles, which may be in the form of spheres, pellets, stones, granules or the like, are carried by the grooves and the centrifugal force towards the top of the drum and drop on to the workpieces which roll and tumble in the lower part of the drum. After impinging on the workpieces, the particles because of the presence of the medium, which is only sufficient to coat the particles and workpieces, maintain contact with and slide along the surface of the workpieces to effect a finishing treatment. The particles may be re-cycled through the drum by the use of a pump, and any losses of the medium made good by a dosing pump. The medium may contain a cleaning agent and silicone. In another embodiment, the drum is in the form of a prismatic, for example, three-sided, shell.
